TCOPY(1) OpenBSD Reference Manual TCOPY(1)
NAMEtcopy - copy and/or verify mag tapes
SYNOPSIStcopy [-cvx] [-smaxblk] [src [dest]]
DESCRIPTIONtcopy is designed to copy magnetic tapes. The only assumption made about
the tape is that there are two tape marks at the end. tcopy with only a
source tape (/dev/rst0 by default) specified will print information about
the sizes of records and tape files. If a destination is specified a
copy will be made of the source tape. The blocking on the destination
tape will be identical to that used on the source tape. Copying a tape
will yield the same output as if just printing the sizes.
The options are as follows:
-c Copy src to dest and then verify that the two tapes are identi-
cal.
-smaxblk
Specify a maximum block size, maxblk.
-v Given the two tapes, src and dest, verify that they are identi-
cal.
-x Output all informational messages to the standard error. This
option is useful when dest is /dev/stdout.
